It's a known kernel bug that Dell bluetooth is broken in kernels >=4.14, so sticking with the old kernel that works for now.

Kernel bluetooth bug causes bluez 97-hid2hci.rules udev rule to fail.
systemd-udevd has always consumed 100% whenever a udev rule fails (could be argued that's also a bug but at least you become immediately aware there's a problem).

Possibly no coincidence that the break was introduced at the same time kernel tree commits were made to btusb.c wrt. Dell 'features' being addded.
